Figs. 3 View FIGURES 3 E–F, 6 E–F, 9 C–D, 10 J, 13 E–H, 46 A–H.

Male and female. General habitus brown with numerous tiny yellow spots. Eyes and ocelli black. Face pale yellow, frontoclypeus and clypellus dark brown with a median pale yellow stripe extending to base of clypellus, clypellar suture dark brown. Forewing venation light brown, interrupted by dark brown spots. Lateral stripe on thoracic pleura dark brown interrupted by pale yellow. Hind femoral apices, tibiae and tarsal segments black, setae on hind tibiae dark brown to light brown ( Figs. 3 View FIGURES 3 E–F, 6 E–F, 9 C–D). Female seventh sternite with posterior margin slightly convex, with median concavity, lateral margins conically rounded, slightly produced posteriorly ( Fig. 10 J View FIGURES 10 ).

Male genitalia. Pygofer in lateral view triangular, setose throughout, with small rounded caudodorsal lobe and digitate process on caudoventral margin ( Fig. 46 H View FIGURES 46 ). Subgenital plate long, inner lateral margin slightly sinuate, apex somewhat truncate, with setae ( Fig.46 D View FIGURES 46 ). Style symmetrical, broad at base, apophysis of uniform width in basal ¾, narrowed towards apex ( Fig. 46 E View FIGURES 46 ). Connective with lateral margins strongly sinuate, longer than wide at base with distinct median ledge extending entire length ( Fig. 46 F View FIGURES 46 ). Aedeagus slightly curved in apical 1/ 3 in lateral view, with four short, glabrous and one long, spinose subapical processes, gonopore subapical on spinate process, dorsal connective sinuate ( Figs. 46 View FIGURES 46 A–D).

Female genitalia. Valvulae I in lateral view sculptured in apical ¼ ( Figs. 13 View FIGURES 13 E–F). Valvulae II with basal teeth on dorsal margin, toothed on apical ¼ ( Figs. 13 View FIGURES 13 G–H).

Measurements. Male 6.5−6.7 mm long, 1.8 mm wide across eyes and 2.0 mm wide across posterolateral angles of pronotum. Female 7.8−8.0 mm long, 2.1 mm wide across eyes and 2.5 mm wide across posterolateral angles of pronotum.

Etymology. This species is named after one of its host plant genera, Piper   .

Remarks. T. piperica   sp. nov. resembles T. tripectinata   but differs in having five subapical processes on the aedeagal shaft compared to three in the latter species. The gonoduct extends into the spinose subapical process of the aedeagal shaft and opens slightly before the distal end ( Figs. 44 View FIGURES 44 A–B). A similar situation is also found in Olidiana peniculata   .
